Neutrophilia
Neutropenia
Eosinophilia
- Eosinophilia an increase in numbers of eosinophils in the blood/tissues
- Occurs in:
- Parasitism or hypersensitivity.
- The antigens of both may sensitise T-lymphocytes, and re-exposure to the agent may result in quite substantial numbers of eosinophils.
- Some breeds of dogs, e.g. German Shepherd.
- Parasitism or hypersensitivity.
- Are prone to developing eosinophilia.
Eosinopenia
- Eosinopenia is a reduction in the number of eosinophils in the blood.
- Occurs as part of the response to corticosteroids;.
- Thought to be associated with the depressive effect of corticosteroids on lymphocytes.
- Secretions of these lymphocytes are thought to stimulate eosinophil production.
Lymphocytosis
- Lymphocytosis is an increase in numbers of lymphocytes in the blood.
- Occurs:
- In tumours in which there is a substantial increase in their number.
- Some of the lymphocytes are immature - lymphoblasts.
- For example, Bovine Leukosis.
- Following adrenaline release in fear, excitement and so on.
- In some cases of chronic infection.
- However, reactive hyperplasia in associated lymph nodes may not correlate with the numbers of circulating lymphocytes.
- Commonly in growing swine.
- In tumours in which there is a substantial increase in their number.
- Possibly associated with aMycoplasma infection.
Lymphopenia
- Lymphopenia is a redcution in the numbers of lymphocytes in the blood.
- Occurs in:
- Viruses that attack the lymphoid system.
- For example:
- Canine Distemper
- Infectious Canine Hepatitis
- Feline Infectious Enteritis
- Bovine Virus Diarrhoea.
- For example:
- Irradiation
- Corticosteroid therapy.
- Selectively suppresses lymphocytic activity, and the inflammatory response in general.
- Viruses that attack the lymphoid system.
- Other immunosuppressive drugs may act in a similar way.
Plasma Cells in Blood
- Plasma cells are rarely observed in blood.
- If many plasma cells are present in blood, it is due to a plasma cell tumour that has begun to metastasise.
Monocytosis
- Monocytosis -is an increase in numbers of monocytes (haematogenous macrophages) in the blood.
- Occurs:
- In conjunction with neutrophilia in fear, excitement etc.
- In the chronic stages of bacterial disease.
- Monocytes very rarely behave as macrophages in the blood.
- However, this is seen in cases of severe intravascular haemolysis of red blood cells where remnants of the RBC's are found in their cytoplasm.
